Multi channel use?

Am I correct in understanding that this can be used for multi channel use? If so what parts would be necessary for a 6 or 8 channel volume control please?

Hi Rob,

For 8 channel you will need one controller board and 4 stereo relay boards.
Relay boards will be connected on top of each other.
Please contact me at office(at)vicol-audio dot ro for further info.
